L ATHROP AND EDWARD CLYDE HOGE ROOF AND FLGOB CONSTRUCTION y Application filed February 19,.'1924. ASerial llo'iz` 4 My invention relates to construction of roofs and fioors of monolithic character, particularly where poured from gypsum plaster, or like light weight ceramic product.

In my Patent No. 1,464,711, dated August 4th, 1923, I show and describe a floor and roof construction wherein a sheet of composition board is employed as a permanent under support for the poured eementitious body of the roof or floor, said plaster board being mounted on the bases of metal rails.

It is my object in the present invention'to obtain like advantages in metallic reinforcement and support of a poured gypsum plaster construction, but to use a removable form as a support. The structure made according to the new invention, has greater depth than the first form devised by me, as set forth in said patent, and in addition the rails 'are or may be entirely enclosed in a body of plaster, while the reinforcing arch of wire mesh, rods or expanded metal that is supported across the rails is deeper in its supporting arch.

The removable supports are not destroyed with use, and can be used over again, and in avoiding the use of plaster board, I eliminate the necessity of care and attention in handling of this form of floor and roof support.

That is to say, there is eliminated the chance of breakage of the composition board, since the use of the same is done away With, without any disadvantageous results.

I accomplish my objects, which generally speaking vare the advantageous features of my former invention, applied to other than a composition board supported structure, by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Figure 1 is a perspective of the form work for my new structure.

Figure 2 is a like view of the poured slab.

Figure 3 is a cross section of the poured slab ybefore the under form is removed.

Referring to the illustrated embodiment of my invention, 1 are the channels of a building, typifying whatever structural metal girders, beams or trusses that may be used inthe roof or lioor.

ranged in spacing, as the rails are spaced.v

The planks are in number enough to span the spacer between the beams or trusses, or else the planks may be built up, as has been my practice in boards of three planks each bat-v tened together,suiiicientboards being used tospan thebeams.

Vhatever form` of -support is used, the

forms are suspended from the rails by means of suitable ties, such as'wire ties T, and the space between the fstructural'beanis is closed off, so as to permit of supporting the poured cement.

rIf boards made up of planks and battens are used, the battens are set beneath the rails and holes bored in the planks throughwhich the Wire ties maypass, so that the Wires pass around the battons.

When theforms are set up, the next stepl is tolay in the mesh. y This is done by looping somesuitable open-work metal structure crosswise `of therrails. As an illustration 'I havefshown partially diagrammatically, the

wire mesh 8.*1 n

This metal structure of rails running one way of the beams, and wire mesh in arches transversethe rails, gives excellent support, and the use .of rails is preferred for one reason, because the tops or balls are rounded and do not tendto shear the wire mesh., when subjected to strain. i n

Furthermore .the use of the rail `formof cross" support is preferred because of the double channel form, providing for a keying in of the poured plaster or cement body.

I pref-er to further increase the keying in, by so arranging the ties, for the forms, that assente they are `suspendued below the rails. In Figof gypsum plaster, because of its light weight, is poured into the form so builtrup, and will liow entirely around the rails, being held by the suspended under forms. Preferably the slab should come above the tops of the rails to thoroughly .embed the mesh.

When the structure is poured the lower forms are removed by cutting the wire lying beneath the battens, whereupon the forms will drop away. i

In building the roof or floor, the operators can walk about more freely where the under form is removable, as compared to the instance in which plaster board is mounted on the bases of the rails, since there is no danger of stepping onto the under forms, and no likelihood of breakage ofthe under forms, Also many prefer a ceilingwhich does not show the plaster board forms interspaced by the rails.

The rails lie direct on the beams or trusses, and the wire mesh forms deep arches in support across the rails, so that to a very large degree there is no strain left on the poured plaster element of the slab.

Having thus described one illustrative embodiment of my invention, what I claim as new and desire to secure by Letters Patent, 1s:-

l. A roof or oor structure comprising in combination with interspaced girders, interspaced supporting barsV disposed crosswise on the girders and mounted thereon, with rounded upper portions, reinforcing metal disposed across between the bars, said metal disposed over the rounded upper portions of the bars and extending in concave arch formations between the bars, and poured cementitious material enclosing the reinforcing metal and forming with the lower surfaces of the interspaced bars an unbroken under surface for the structure.

2. A roof or floorstructure comprising in combination with interspaced girders, interspaced supporting bars disposed crosswise on the girders and mounted thereon, with rounded upper portions, reinforcing metal disposed across between the bars,said metal disposed on, but not secured to the bars, and said metal extending loosely in concave arch formations between the bars, and poured cementitious material completely enclosing the bars and forming with the lower surfaces of the interspaced bars an unbroken under surface for-the structure.
